What do you use to polish front rail and balance rail pins? I use BRASSO polish. Is this ok? Is there anything better? How do you treat badly corroded front and balance rail pins other than replacement? I've used steel wool and it solved the problem, but I've been told it nicks the finish and will lead to premature key bushing failure. Finally, does anyone market a cleaning tool for these pins? Danny Boone describes one in his book, but it requires a used case from a hypdermic syringe. These are not readily available. ...looking forward to your advice. -- Frank Cahill Associate Member, Piano Technicians Guild Northern Va
